Biggest argument for free college in USA:

Assume constants x amount of hard work will pay for y amount of college.

My dad (1955-59): Bailing hay over summer paid for 2 semesters (tuition and board)

Me (1982-1986): minimum wage job over summer (not 40/week) paid for 1 semester (tuition only)

My son (2012-2016): minimum wage job for summer (40/week) would pay 35% of a semester (tuition only).
